Application 'led February 17, 1921.

T0 all fwwm'e't may concern.'

' Be it known that Ezniiinn FIELD WHITE,

l a citizen of the United States of America,

and a resident of Detroit,r county of Wayne, State of Michigan, have invented certain Vnew and useful Improvements in Paint-Shop Appliances, of which the following is a specification.

This invention relates mainly to metho-dsand means adapted to facilitate applying paint, varnish-and other coatings to vehicle bodies and other articles, and to means for recovering surplus coating materials or drippings from the articles treated.

rllhe main objects of the invention are to provide an improved system of apparatus adapted for carrying on a continuous process in the application of coatings to the goods treated; to provide coambulant carrier and y "lciently to permit drainage of fluid coating platform means for the goods and operators respectively; to provide an improved form of platform and operating mechanism therefor; to provide automatic means for positive coaction of the' carrier and platfori'n;

to provide in combination with a moving platform and carrier to collect surplus material or drippings when a wash or flow coat- Y ing is applied to goods on the carrier; and to provide for use in connection with a flow system of applying coatings, a perforated platform, a drip collector and circulating means to return the recovered material to its source or supply tank.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which- Figure l is a side elevation in somewhat diagrammatic form of coambulant conveyer and platform members adapted for rcarrying the operatorsalong with the work while lapplying the coatings, only part of the conveyer being shown.

Fig. 2 is a view taken transversely of l substantially on the line 2-2 of said ligure.

ln the construction shown -in the drawings, the endless conveyer l and the endless platform 2 are positively connected by a belt or sprocket chain 3 whereby the-travel speeds of the platform and work carriers a are coequal at all times regardless of variations in the absolute speed.

The conveyer l is to be understood as including a pair of endless belt members or chains 5 between which the carriers et are suspended and a series of stationary bear- -wardly `convergent sides.

ings 5 substantially as set forth in my copending application, Serial No. 439,137. Said conveyer extends through a drying room (not shown) Vand through a continuous circuit, aswill be understood, though only a part of the conveyer adjacent to the platform 2 is here shown.

The platform 2 is disposed directly beneath and parallel with the con'veyer l with ample space for clearance of the depending carriers. Said platform is surrounded by a stationary platform 6. The moving platform comprises a pair of endless belt or chain members 7 spaced apart in parallel relation anda series of floor sections 8 by which said members are connected at intervals along their length. Each floor section Scomprises a plurality of cross members 9 such as boards, planks, bars or the like spaced apart sutil- ",respond with the working area of the platform, and comprises a plurality .of compartments 1l merging together'at their adjacent edges 12 where the pan as a whole is shallow.

,Each section'll is provided with a trough-l like bottom of conoidal shape withzdo'wnextremity of each pan section con'u'nunicates as at 13 with a discharge pipe lli leading to a common return main 15. A pump l'is connected in said main and delivers the recovered material to the tank 17 where it is again Vavailable for use.

The carrier 4 and platform sections 8 are arranged alternately in succession so that saidplatform section shall provide standing room forthe operator between'the carriers. The platform is entirely open directly under the carriers so that the greater part of the drippage may fall directly into the pan l0. This mutual relation of the carriers and platform sections is maintained permanently by the positive connection 3 above mentioned. Suitable sprocket wheels 18 and i9 and gear wheels 20 are arranged in connection with chains 3 to ell'ect synchronous speeds for the platform 2 and carriers 4:. The carriers 4 are of open frame construction to permit of ready loading and unloading and to give the workmen access to the work 2l for applying the coatings usually in wash form. ln

The Vdownw ardl the drawings the carriers are eachshown loaded with a vehicle body.

Whenthe deviceis kin operation the articles to be treated are placed on the carriers successively at a loading station, not shown. The conveyer moves slowly at about two or three feet per minute. As the carriers pass over the synchronously moving platform 2 Y' in registry with the corresponding drip apertures 22 therein the operatives standing or walking upon the platform sections S direct `the wash .material upon the goods vto be coated. Said material is ysupplied through a hose as `understood inthe art, though not here shown. All surplus material drains into the pan l0 through the floor openings 22 and to some extent through the Hoor cracks in sections 8 y Then automobile bodies,l for instance, are being treated the operator passes in between two carriers, washes the side .of one body, turns and washes the side ,of the next body, then walks around the rear end of the body which is also washed,fand then in between the second mentioned body and the next ad- K Y jacent or third body, andso on, in the vdi- .rection from whichfthe work approaches.

The speed off the conveyer, thedrying room A length and the working speed vof theworlrman and washY nozzle are-allmutually Y i usted for a maniinumVV speed consistent efficiency'. Y* ,y .c v Y Due .coturning of the driving lsprockets 18 -onoppositey ends of the aideshafts"l 23 V is insured by fastening saidv members together rigidly Said shaftsl 23 are journaled inl bearings. 24 set in the vplatform support-ing j frame 25'. Level alinement offtheplatform betweenl the upper sides of the sprocket wheels 18 is provided for bywmeans of the l,guiderails 26 securedvto .frame 25 whereon thispart of the platform fis slidingly supported.V Supportingguidesg27 may also be provided for the platform adjacent to the HOOTQS. The 'means for supporting the conveyer 1 and the means 29 and 30 to prevent tipping or tilting ofthe carriers 4 when moving ,horizontally are more fully shown and described in my said copending application.

VAlthough but one specific embodiment of this invention is herein shown and described,V

it will be understood that numerous details of the construction shown may be altered -oro1nitted without departing from the spirit lreceive articles to be treated arranged to pass said articles along the length of the upper part ofV said' platform, said conveyer and platform being positively connected for corresponding travel speed.
